The president facing tough questions, too. He just landed in Warsaw, Poland. Jon Karl is there. And despite the backlash, the president making no apologies for the deal. Reporter: Exactly, George. We just heard from the president at a joint press conference, with the president of Poland. He was asked directly about this controversy. And he says there is a sacred rule of the U.S. Military, that we leave no man or woman in military behind. Regardless of the circumstances, whatever those circumstances may turn out to be, we still get an American soldier back in he's held in captivity. Period. Full stop. Reporter: But, George, that is an answer that is unlikely to stop all of the criticism the president is getting from the circumstances surrounding this prisoner trade. And the president getting questions about the prisoners released in Qatar. They're going to be living in luxury villas. The question is, has the president gotten the assurances the law requires that these Taliban leaders will not return to the battlefield? Reporter: The white house, the president himself, says he has received those assurances. As you see, they're going to be living in beachfront villas in Doha. Very upscale neighborhood. But the white house says the president received personal assurances from the government of Qatar that they would not go back into the fight. And today, the president said if they did go back into the fight, that the United States would not hesitate to go after them again. Okay. Jon Karl with the president this morning. Thanks.
